Problem: No voltage detected at heater relay—failed relay on control board or open thermistor circuit
How to Fix Dryer Error
- Disconnect power and remove rear panel.
- Locate main control board and identify heater relay terminals.
- With power restored briefly (CAUTION), use multimeter to verify 120V AC present at relay input terminals during heat cycle.
- If input voltage present but no output to heater, relay has failed—control board must be replaced.
- If no input voltage, test inlet thermistor WP35001191 resistance (should be 10k-12k ohms at room temp).
- Replace thermistor if out of range.
- If thermistor good, check wiring harness between thermistor and control board for breaks or corrosion.
- If wiring intact and thermistor good but relay still not energizing, replace main control board WPW
- After repair, verify heater operation by measuring voltage at heating element terminals during cycle (should read 240V for electric models).
- Monitor exhaust temperature to confirm proper heating (135-155°F typical).
Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
